Not really. The primary issue with Bitcoin x quantum computers is that older Bitcoin transactions contained a full public key (and not a fingerprint / wallet address), so a quantum computer could manipulate that to make a false signature on wallets including Satoshi's (this would be obvious and detectable if someone starts moving very dormant coins). For the larger network there are some other points where it becomes an issue, but before then you'd need to fix HTTPS web traffic and PGP, too. https://www.deloitte.com/nl/en/services/risk-advisory/perspectives/quantum-computers-and-the-bitcoin-blockchain.html https://www.deloitte.com/nl/en/services/risk-advisory/perspe...
